SPOT-LIGHT SONG AND LECTURE LANTERN-SLIDE.

I Specification of Letters Patent.

Patented Nov. 28, 1911.

Appliation filed August 19, 1911. Serial No. 644,914.

To all whom it may concern,

Be itknown that I, FREDl-IRHK A. Arronnauw, a citizen of the United States, and a resident oi the city ot' New York, borough of Manhattan, in the eountv and State of New York, have invented a new and Improved Spotdiight Song and Lecture Lantern-Slide, of which the following is a full, clear, and exact description.

Among the prineipal objects which the presentv invention has in view are: to provide a lantern slide for employment in connection with illustrated songs and lectures, having a clear space. therein to form an illuminating area for the disclosure of the entertainer; and to provide in a lantern slide of the character set forth a clear area within the [ield of the photograph to form a spotlight for the illumination of the entcrtainer.

One emhodinient of the present invention is disclosed in the structure illustrated in the accompanying drawings. in which like eharactors of reference denote corresponding parts in all the views. and in which- Figures 1, 2. 3 and 4 are views of lantern slides constructed and arranged in aecordance with the present invention.

As shown in the accompanving drawings, the slides are provided with the usual frame 9, and the light area or field 10 on which the transparency or photograph is printed. in

a preferred location, and one suitable for the purpose, is formed a clear space or light spot 11. in the usual formation of the slides,

the spot 11. is so disposed on the slide as to he t'ormed 0r surrounded by a darkened portion of the slide. as will be seen by reference to the views in the present. drawings.

The si nv and shapeof the spot 11 is varied tosuit the needs of the pl-iotograph or the desire of the entertainer. As shown in the drawings the spot is circular in form, havin a saw-toothed or star-shaped perimeter or edge.

While T have herein shown the spot as being: contained within the field 10, I wish it, understood that the spot may he formed on the slide in the frame 9 and exterior tothe field 10. Again, it' it is wished, the spot may be contained partially within and without the perimeter of the said field.

The invention is eonsidered hymebroadly to consist in the. l"()lI]ltltl0I\ in the slide. itself that the illumination of the of a light spot. into which the entertainer 5 moves when the picture is projected upon the screen usually employed as connter-distinguished from the employment of a separate instrument or so-called light spot; for illuminatingor disclosing the entertainer. 6 When employing slides of the character described and shown the pictorial. ettects are produced as with the usual or ordinary slides. It will be found that in each case, when constructed in accordance with this 6 invention. the light spot 11 forms a ray or path of light which produces on the screen a clear blank space, or what. is known as a spot light. During the entertainment the entertaincraisinger or speaker, moves so 7 that his or her head comes within the illuminated area and forms thereby an illumination seemingly comprising or composing a portion of the picture projected upon the screen. 7

Bevond the advantages due to the fact erson of the entertainer incorporates the picture thereof into the picture on the screen, a further advantage is gained in that there is not re quired a second mechanism or lantern, nor is the entertainment marred by the disadvantage of the necessary partial illnmina tion of the space oeeasioned by the use of. the second lantern to produce the spot light; ahove referred to.

Having thus described my inventiomwhat I claim as new and desire to secure by Let.- ters Patent is 1. A lantern slide having a clear area to form a spot light.

2. A lantern slide having in the field thereof a clear area to form a spotli ht.

A lantern slide having eoin lete ywithin the field thereof a defined 0 ear area .to form a spot light. I

4. A lantern slide having a clear MZOXLBYP l tirely comprised within the field of said slide to form a spot light, the edges of said are;

being shaped to form a frame for said spot 100 light In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
